We are withdrawing the immediate final rule for Montana: Final Authorization of State Hazardous Waste Management Program Revision published on May 9, 2000, which approved the third revision to Montana's Hazardous Waste Rules. We stated in the immediate final rule that if we received comments that oppose this authorization, we would publish a timely notice of withdrawal in the Federal Register. Subsequently, we received comments that oppose this action. We will address these comments in a subsequent final action based on the proposed rule also published on May 9, 2000, at 65 FR 26802.
